Abstract
The invention discloses an anti-pinch force testing method of an electric car window in a car door anti-pinch system. The anti-pinch force testing method includes step 1, checking and recording (also called inspecting) whether testing conditions and testing equipment are normal or not, especially whether the anti-pinch door window has anti-pinch action or not and whether values indicated by a force meter can be reset or not; step 2, uniformly selecting three points on the car window as testing points, and measuring three times on each testing point, namely measuring nine times in total. By the anti-pinch force testing method, factors like positions, steps, data processing and result judgment of anti-pinch force testing are standardized, so that operability and specificity in testing are realized; system errors are avoided in testing results as much as possible, so that an anti-pinch function of the anti-pinch system is reflected more objectively.
Description
Technical field
The present invention relates to a kind of method of testing of anti-grip force.
Background technology
Along with the development of auto industry, to the requirement of automobile from the past durable in use to first the transition of safety and comfort direction, the anti-pinch of automobile electric window requires also more and more higher, from qualitative by now quantitative in the past, defines a series of requirement.Proposed anti-grip force before being greater than 100N in GB 11552-2009 " the inner ridge of passenger car " standard, motorized window should bounce back.Encounter many troublesome problem in the process of implementation.The first, in measuring process, owing to there being the difference of measurement point, motorized window has a clockwise or counterclockwise rotation trend, thus causes the movement interference between vehicle window and glazing tape, causes the change of anti-grip force.The second, pendulous frequency is very few, and result sample is lower, has certain one-sidedness to problem analysis, easily ignores because of objective factors such as occasioned anti-grip force changes.Three, pass judgment on criterion, because of whole anti-grip force reaction is the system ensemble problem of the parts such as vehicle window, sealing strip, how to utilize measurement result most important in the influence factor of whole system to pass judgment on its each parts well.Therefore how to measure anti-grip force and become a key problem to the objective evaluation of whole system, for this reason, criterion position, measuring process, the series of problems such as measuring method are essential.
Summary of the invention
The technical problem to be solved in the present invention is: for the problems referred to above existed during anti-pinching car window Force meansurement, provide a kind of method of testing as far as possible can avoiding error.
Technical scheme of the present invention is:
In automobile door anti-clamping system, an anti-pinch force test method for power windows, comprises the following steps: step one, checks, records (or claiming spot check) test condition, whether rig for testing is normal.Particularly anti-pinch door and window is with or without anti-pinch action, and whether dynamometer indicating value can back to zero; Step 2, vehicle window is evenly chosen as test point at 3, and each test position point is measured 3 times, carries out 9 times altogether and measures.
In step 2, three points chosen are respectively 1/4L, 1/2L and 3/4L point, and wherein L is vehicle window length.
Choose the measurement result of the maximal value in measuring for 9 times as the anti-grip force of automobile electric car-window.
Choose 1/2L position 3 times measure in a maximum measured value as the anti-grip force measurement result of anti-clip module or switch.
Beneficial effect of the present invention:
The specification position of anti-pinch Force meansurement, the key elements such as the process of step, data, the judge of result, make test have operability and definition, and the result of test avoids systematic error as far as possible, reflect that the pinch resistant functionality of anti-clipping system is more objective.
Embodiment
Measuring process:
Step one, checks, records (or claiming spot check) test condition, whether rig for testing is normal.Particularly anti-pinch door and window is with or without anti-pinch action, and whether dynamometer indicating value can back to zero.
Step 2, door and window is evenly chosen at 3 and is respectively 1/4L, 1/2L and 3/4L as test point, and wherein L is vehicle window length.Each test position point is measured 3 times, carries out 9 times altogether and measure.
Data processing
A) measured value maximum in measuring for 9 times using three measuring positions place is as the measurement result of the anti-grip force of automobile electric car-window.
B) measured value maximum in measuring using 1/2L position on door and window 3 times is as the anti-grip force measurement result of anti-clip module and (or) switch.
4 pass judgment on criterion:
When a) evaluating door device performance, get 3 positions 9 times measure in maximal value as evaluation index.
If this value < 100N, illustrate that the anti-grip force of whole door device meets the demands.
If this value >=100N, illustrate that the anti-grip force of whole door device is discontented with sufficient requirement, not certain part does not meet the demands.Need progressively to analyze association parts such as door and window, motor, electric control module and (or) switches further.
When b) evaluating control module and (or) switch performance, to get on 1/2L position in measuring for 3 times maximal value as evaluation index.
If this value < 100N, illustrate that control module and (or) switch performance meet the demands.
If this value >=100N, illustrate that control module and (or) switch performance do not meet the demands.
